looks very similar to the RJ-45 interface, but the SC interface appears more flat, the obvious difference is the inside of the contact, if it is 8 thin copper contacts, it is the RJ-45 interface, if a copper column is SC fiber interface.LC Fiber COUPLER: Applied to the LC fiber interface, the connector that connects the SFP module, it is made of the easy-to-use modular jack (RJ) latch mechanism. (routers commonly used)FC Fiber Coupler: Applied to FC

Experience Improvement Program:The Vsphere Customer Experience Improvement Program was introduced to collect vsphere configuration data and transfer it to VMware for analysis on a weekly basis to help VMware understand usage and improve the product.Iii. issues addressed by VMware VSphere 5.5 Update 2 (a) The issues addressed in the server configuration are:1. You cannot connect to an NTP server when you configure multiple NTP servers through the VSphere Web Client2. The host profile answer file
all users can not access the Internet. On-site observation of the core switch corresponding to the parallel port and Convergence Switch Connector Fiber module Connection LEDs are not lit.
Cause analysis: After replacing the good SFP light module, the new fiber jumper and the redundant two-core fiber, the network did not return to normal, so the fault may appear on the cable between the core switch and the converging switch.
Reason 1: Campus network
Fast Ethernet and Gigabit Ethernet line cards
The Cisco Catalyst 4500 series scalable, modular, and high-density switches provide superior combined second-layer switching and intelligent services, which enable network control and sustainability. These switches provide a wide range of Fast Ethernet and Gigabit Ethernet line cards, including the desktop, branch backbone and servers for enterprise and commercial Exchange solutions, and the fiber and copper interfaces optimized for service Supply m
function, supports VLAN division, and provides redundant power interface.
Although for layer-3 Switch, DES-3326 performance in general, support expansion slot is relatively small, but the low price is also in exchange for good cost effectiveness. DES-3326 switches are suitable for medium and small network core layer and large campus network convergence, providing Gigabit Ethernet modules can be connected to high-speed backbone network, to effectively alleviate network bottlenecks.

to know whether the expected service is available at the outlet. The network owner also wants to know:
At what rate can the network be connected?
Can this outlet provide power for VoIP phones?
Can I access the Internet?
Can I use a network printer?
DTX-NSM network service module can provide answers.
At what rate can the network be connected?
